How many days has it likely been since a 3-month-old with RSV last saw an infected cousin?

3 days
6 days
10 days
14 days

The correct answer is: 6 days

The timing of RSV (respiratory syncytial virus) transmission is often linked to an understanding of the incubation period and viral shedding. Typically, RSV has an incubation period of about 4 to 6 days, meaning that if a child was exposed to an infectious individual, symptoms may onset within this timeframe. Given that it has been mentioned that it has likely been a certain number of days since the 3-month-old last saw the cousin who was infected, choosing a duration aligned with this incubation period is crucial. Selecting the choice of 6 days reflects a recognition of the upper limit of the standard incubation period. This timeframe suggests that the child might have been exposed shortly before or around the onset of symptomatic RSV, making 6 days a plausible duration since the last exposure. This makes the chosen answer fitting within the context of typical RSV transmission dynamics and potential contagiousness around the time of interaction.
